Answer:

\boxed {m = -\frac{3}{4}}

Step-by-step explanation:

Use the <u>Slope Formula</u> to help you determine the slope of the two following points:

m = \frac{y_{2} - y_{1}}{x_{2} - x_{1}}

(where (x_{1}, y_{1}) is the first point and (x_{2}, y_{2}) is the second point)

-Apply both points to the formula:

(x_{1}, y_{1}) = (-2, 1)

(x_{2}, y_{2}) = (2, -2)

m = \frac{-2 - 1}{2 + 2}

-Solve:

m = \frac{-2 - 1}{2 + 2}

m = \frac{-3}{4}

\boxed {m = -\frac{3}{4}}

Therefore, the slope is -\frac{3}{4}.

Answer:

-3/4 is the slope.

Step-by-step explanation:

Use this formula to find slope.

y2-y1/x2-x1

PLUG IN

-2 -1/2- (-2) = -3/4

The slope is -3/4

(x-1)(x+2)=5(x-1) divided by x-1
anyanavicka [17]
Assuming that your question is (x-1)(x+2) = [5(x-1)]/x-1

On the right side, the x-1's will cancel out, leaving you with (x-1)(x+2) = 5

expand the left side, giving you x^2 + x -2 = 5
which goes to x^2 +x -7 = 0
the possible values for x are 2.93 and -3.93. I don't think this was your question, so I'll do the other possible question that you might have been asking.

(x-1)(x+2) = 5(x-1)

divide by x-1 on both sides, leaving you with x+2=5
x+2=5
x=5-3
x=3

Find the value of two numbers if their sum is 112 and their difference is 66.
snow_lady [41]

Answer:

x+y = 112 ........ (1)

x-y = 62............ (2)

from (1) and (2)

2x = 174

x = 174/2

x = 87

sub x = 87 in (1)

x+y = 112

87+y = 112

y = 112 - 87

y = 25

so the numbers are 87 and 25

Can someone plzz help me you got to zoom in !!!
daser333 [38]

1. 140 - The reason it would be one 40 is honestly a really simple explanation. Is the ratio of boys to girls in 7-2 and the amount of girls is 40. That means that per 1 number, is 20 people since 40 divided by 2 is 20. So if I do 2 x 7 that would be 140.

2. I didnt really understand this one sorryyy.

3. 1200 (same rule applies) - Since The ratio is 1:11 and the 1 represents 100 beans. If I doo 100 x 11 that would be 1100, then I would add the 1100 to the 100 (from the 1) and that would be 1200.

4. 6:7 - If I do 650 - 350 that would be 300. Which means the ratio would be 300:350. But once simplified the answer would be 6:7.

5. 1:2 - 720 - 240 is 480. Therefore the ratio would be 240:480. Once simplified, the ratio is 1:2.

Hope this helped. Good luck!!! xo
